We begin in the Town of Fenton, where a mudslide pours into traffic on Interstate 88.

This is Steve Major's truck after getting plummeted by a landslide on Interstate 88 in the Town of Fenton.

"Mud, rocks, trees. When the 3rd slide came down I saw cars flying. The mud just throwing them across the highway," says Major.

Police say the landslide came pouring off a steep embankment.

It crossed all 4 lanes of traffic, hitting some cars; injuring several people.

One was seriously injured.

"I saw tail lights flying through the air," says Major.

Police shut down I-88 east and westbound between exits 1 and 3.

Drivers were ushered off the highway.

"The whole side of the mountain just came down," says Major.

Witnesses at the scene say there were three separate slides.

"The first one came down before we got there, covered one vehicle. I guess there was a woman and a little girl. And then we were standing there, waiting. And then the next thing you know, another came down. And you could just smell the dirt," says Theresa Florance of Port Crane.

"Huge rocks, huge rocks. And it's all the way across the center line," says Major.

Front loaders were called in to remove debris and start cleaning up the highway.

"Can you believe this is happening?" asks reporter.

" No. I just want to go home and sit there," says Cassandra Martin of Harpursville.

Broome County now says more than 20 vehicles were involved in the landslide.

Also, I-88 westbound is now open, but the eastbound lanes remains closed in that area.
